The Under Armour WWP Amplify Thermal delivers superior warmth in cold conditions and shows your support for the brave men and women of our Armed Forces. Made with a comfortable blend of polyester and elastane, this loose fitting shirt is part of Under Armour's ColdGear line, making it a great choice for staying warm in temperatures between 0 and 55 degrees Fahrenheit. This shirt is an officially licensed product of the Wounded Warrior Project and features a WWP logo on the left chest. Thanks to the UA Freedom Initiative, a portion of the proceeds from each shirt sold will be donated to support veterans, military personnel, law enforcement officers and first responders.
